About this file
This statement of work outlines requirements for cadmium plating of parts for the Department of the Navy. The plating must meet specifications for coverage with no bare areas, pinholes, or air bubbles, with a maximum thickness of 0.00040 inches for threads and 0.00080 inches for other surfaces. Plating must show no separation when tested per ASTM D3359-95A and meet adhesion requirements. All cadmium plated parts must be baked after plating but before chromate finish, at 375 degrees F for a minimum of 23 hours. The government reserves the right to perform corrosion and hydrogen embrittlement tests.
This federal contract opportunity from the Naval Sea Systems Command seeks offers for the M3A2 housing firing pin E seal. The statement of work provides technical requirements for cadmium plating of parts to be supplied under the contract.

STATEMENT OF WORK (CADMIUM PLATING)
1. Unless otherwise specified, parts are to be cadmium plated to the requirements of AMS-QQ-P-416, Revision E, plus the following
2. Coverage: There shall be no rack marks, air bubbles, pin holes nor any other bare areas, except those specifically denoted as such by the contract/purchase order/or bankcard order.
All internal and external threads shall have at least a presence of plating (verifiable by visual examination) and a maximum coverage thickness of .00040 inches. All surfaces not controlled for plating thickness by the contract/purchase order/or bankcard order shall have presence of plating (verifiable by visual inspection) and a maximum coverage thickness of .00080 inches. These requirements shall be met regardless of part configuration, contour, part size, and any in-process controls needed to perform the plating. (This includes all internal and external surfaces.)
3. Adhesion: Plating shall show no indication of separation from the base metal when tested in accordance with ASTM D3359-95A, and shall meet adhesion requirements of the governing plating specification.
4. Embrittlement Relief: All cadmium plated parts, regardless of hardness, must be baked, after plating, but prior to chromate finish, as specified below. Any parts exceeding R/C 36 (160 ksi) in hardness, shall also be subject to the following baking requirements between stripping and replating.
Time between Plating and Baking: shall not exceed 4 hours
Temperature for Baking: 375 F +/- 25 F
Time for Baking: 23 hours minimum
5. Corrosion and Hydrogen Embrittlement Tests: Although the vendor is not required to perform this test, the government reserves the right to perform the test at any time, at government expense.
